Question

If cot = 40/9 find the values of cosec and sin ?
​

Answer 1

Answer:

We know that cot theta=adjacent side/ opposite side

Here adjacent side=40

Opposite side=9

By Pythagoras theorem ,

(40)²+9²=(Hypotenuse)²

(Hypotenuse) ²=1600+81=1681

Hypotenuse=√1681=41

cosec theta=41/9

sin theta=9/41

Answer 2

Answer:

cosec=41/9 and sin=9/41

Step-by-step explanation:

First use Pythagoras theorem

(AC)2=(BC)2+(AB)2

=(9)2+(40)2

=81+1600

(Ac)2=1681

Ac=√1681

AC=41

Then we find cosec and sin

Cosec=41/9

And Sin =9/41
